2 Connection

Connection of the interface to the AC indoor unit:

Disconnect mains power from the AC unit. Open the front cover of the indoor unit in order

to have access to the internal control board. In the control board locate the socket

connector marked as XYE.

Using a 3 wires cable, connect the EXY connector from the INKNXMID---I000 to the XYE

connector of the AC unit's control board.

Fix the INKNXMID---I000 inside or outside the AC indoor unit depending on your needs –

remember that INKNXMID---I000 must be also connected to the KNX bus. Close the AC

indoor unit's front cover again.

Connection of the interface to the KNX bus:

Disconnect power of the KNX bus. Connect the interface to the KNX TP-1 (EIB) bus using

the KNX standard connector (red/grey) of the interface, respect polarity. Reconnect power

of the KNX bus.

Connections diagram:

Figure 2.1 Default parameter configuration

Please note that address of indoor unit must be set accordingly to the System in

paràmetres dialog. See 4.1.3 Number of Indoor Units in ETS for more information.

IMPORTANT: If the INKNXMID---I000 gateway is not placed at

one end of the EXY bus, the terminal resistor should be

deactivated. Remove Jumper 1 to deactivate the 120 Ω terminal

resistor.

4 ETS Parameters

When imported to the ETS software for the first time, the gateway shows the following

default parameter configuration:

Figure 4.1 Default parameter configuration

With this configuration it’s possible to send On/Off (Control_ On/Off), change the AC Mode

(Control_ Mode), the Fan Speed (Control_ Fan Speed) and also the Setpoint Temperature

(Control_ Setpoint Temperature). The Status_ objects, for the mentioned Control_ objects,

are also available to use if needed. Also objects Status_ AC Return Temp and Status_

Error/Alarm are shown.

The first field shows the URL where to download the database and the user manual for the

product.

Figure 4.3 Parameter detail

4.1.2 Intesis Product

This parameter is used to check, before sending the programing, the maximum number of

AC units your device supports.

Figure 4.4 Parameter detail

Select the version of the gateway that you have:

• INKNXMID001I000, if you only want to control 1 AC unit.

• INKNXMID016I000, if you only want to control up to 16 AC units.

• INKNXMID064I000, if you only want to control up to 64 AC units.

4.1.3 Number of Indoor Units in ETS

This parameter is used to hide/show communication object according to the number of AC

units you need to configure. Value ranges go from 1 to 64.

Figure 4.5 Parameter detail

In case you introduce a number higher than the maximum number of units allowed by your

license, you will get a warning message. This is just for information and will not block the

configuration process. Configurations with more indoor units configured than the ones

allowed by the license will not be downloaded correctly.

4.1.4 First Status Updated to KNX

This parameter defines how fast the status is updated to KNX. Depending on the value

selected, more or less priority will be assigned to this action. As there are so many

parameters available, it is important to consider carefully how to set this parameter.

o If set to “ASAP”, all status communication objects will send its value (if needed).

o If set to “Slow”, all status communication objects will send its value (if needed), but

slower than in the previous option (ASAP).

o If set to “Super Slow”, all status communication objects will send its value (if needed),

but slower than in the previous option (Slow).

4.4 Fan Speed Configuration dialog

Figure 4.18 Default Fan Speed Configuration dialog

All the parameters in this section are related with the Fan Speed properties and

communication objects.

4.4.1 DPT object type for fan speed

With this parameter is possible to change de DPT for the Control_ Fan Speed and Status_

Fan Speed byte-type communication objects. Datapoints Scaling (DPT_5.001) and

Enumerated (DPT_5.010) can be selected.

NOTE: Remember that Fan Speeds are selected in the AC supported features tab (see

section 4.2.2).

o When “Enumerated [DPT 5.010]” is selected, Control_ Fan Speed and Status_ Fan

Speed communication objects for this DPT will appear. Also, depending on the number

of fan speeds selected, these objects will be different.

If this DPT is selected with 2 fan speeds:

The first fan speed will be selected if a “1” is sent to the Control_ object. The second

fan speed will be selected sending a “2”.

The Status_ object will always return the value for the fan speed selected.

If this DPT is selected with 3 fan speeds:

The first fan speed will be selected if a “1” is sent to the Control_ object. The second

one will be selected sending a “2”, and the last one sending a “3”.

The Status_ object will always return the value for the fan speed selected.

Important: In both cases if a “0” value is sent to the Control_ object, the minimum

fan speed will be selected. If a value bigger than “2” (in case of 2 speeds) or bigger

than “3” (in case of 3 fan speeds) is sent to the Control_ object, then the maximum

fan speed will be selected.

o When “Scaling [DPT 5.001]” is selected, Control_ Fan Speed and Status_ Fan Speed

communication objects for this DPT will appear. Also, depending on the number of fan

speeds selected, these objects will be different.

If this DPT is selected with 2 fan speeds:

When a value between 0% and 74% is sent to the Control_ object the first fan speed

will be selected.

When a value between 75% and 100% is sent to the Control_ object, the second

speed will be selected.

The Status_ object will return a 50% for the first fan speed, and a 100% for the

second one.

This parameter shows/hides the Control_ Setpoint Temp +/- communication object which

lets you change the indoor unit setpoint temperature by using two different datapoint types.

19:

o If set to “no” the object will not be shown.

o If set to “yes” the Control_ Setpoint Temp +/- object and a new parameter will appear.

This parameter lets choose between the datapoints 0-Up / 1-Down [DPT_1.008]

and 0-Decrease / 1-Increase [DPT_1.007] for the Control_ Setpoint Temp +/-

object.

4.6.2 Ambient Ref. Temp. is provided from KNX

This parameter shows/hides the Control_ Ambient Temperature communication object

which lets you use an ambient temperature reference provided by a KNX device.

20:

o If set to “no” the object will not be shown.

o If set to “yes” the Control_ Ambient Temperature object will appear. Meant to be

enabled when you want the temperature provided by a KNX sensor to be the reference

ambient temperature for the air conditioner. Then, the following formula applies for the

calculation of real Control_ Setpoint Temperature sent ot the AC unit:

As an example, consider the following situation:

User wants: 19ºC (“KNX Setp. Temp.”)

User sensor (a KNX sensor) reads: 21ºC (“KNX Amb Temp.”)

Ambient temp. read by Midea system is: 24ºC (“Ambient Ref. Temp”)

Up / Increase

Down / Decrease

… 16ºC 17ºC 32ºC 31ºC (Upper limit)(Lower limit)

“AC Setp. Temp” = “Ambient ref. Temp” - (“KNX Amb. Temp.” - “KNX Setp Temp.”)

Temp”) AC Setp. Temp: AC indoor unit setpoint temperature Ambient Ref. Temp: AC indoor unit return temperature KNX Amb. Temp.: Ambient temperature provided from KNX KNX Setp. Temp: Setpoint temperature provided from KNX

Page 22: Interface for integration of air conditioners into KNX TP ...

KNX - (VRF line) User's manual r1.2 EN

22 / 28

In this example, the final setpoint temperature that INKNXMID---I000 will

send out to the indoor unit (shown in “Setp. Temp.”) will become 24ºC –

(21ºC - 19ºC) = 22ºC. This is the setpoint that will actually be requested to

Midea unit.

This formula will be applied as soon as the Control_ Setpoint Temperature and

Control_ Ambient Temperature objects are written at least once from the KNX

installation. After that, they are kept always consistent.

Note that this formula will always drive the AC indoor unit demand in the right

direction, regardless of the operation mode (Heat, Cool or Auto).

o If set to “Initial state for each Indoor Unit might differ”, different initial status my

be defined for each indoor unit individualy.

In both cases, there 3 different initial statuses:

• Do not initialize: The INKNXMID---I000 will not modify the current status

after a gateway re-start.

• Start Unlocked: The INKNXMID---I000 will set the remote lock to “unlocked”

after a gateway re-start.

• Start Locked: The INKNXMID---I000 will the remote lock to “locked” after a

gateway re-start.

4.8 Addressing of Indoor Units
